CENTRIFUGAL MACHINE.

v SPECIFICATION forming part of Letters VPatent No. 696,130, dated March25, 1902.

Application filed July 2, 1901.` Serial No. 66,861. (No model.)

To all whom t may concern:

Be it known that I, JOHN JOSEPH BEREI- GAN, of East Orange, Essexcounty, New Jersey, have invented a new and useful Improvement inCentrifugal Machines, of which the following is a specification.

My invention relates to a centrifugal ma! chine wherein solids andliquids are separated,the two constituents being continuously ejectedwhile the apparatus is in operation.

My invention consists in a receptacle for the combined constituents tobe separated rotary on an eccentric axis and provided with a perforatedvessel to receive said constituents; also, in said receptaclehavingarotary perforated vessel for the same purpose; also, in the combinationof the cylindrical receptacle, the cylindrical rotary perforated vesseltherein, and Scrapers on the exterior of said vessel constructed toremove the solid constituent deposited on'the interior of saidreceptacle and convey the same to an outletopening; also, in the Variouscombinationsy more particularly set forth in the claims.

In the accompanying drawings, Figure 1 is a vertical section on thelinear a: of Fig. 2.

Fig. 2 is a plan view. n Similar numbers of reference indicate likeparts.

- The supporting-standard 3 of the machine is preferably cast in' onepiece With the cup 4.

ery. A gasket 11 may be interposed between cover and drum.l In cover 9is a flanged plug 12, supporting the inlet-conduit 13. Secured on theunder side of the cover is a plate 15, having channels 16. The materialentering receptacle 8 by conduit 13 passes through the v channels 16 andis ejected therefrom by centrifugal force. In the wall of receptacle 8is an opening l8,which communicates through a conduit 19,formed in plate2O ,with a smaller opening 21 in the wall of the drum. The openings 18and 21 and conduit 19 together form a passage through which the solidconstituent of the material under treatment is ejected from the 'machineby centrifugal force.

The liquid constituent flows from vessel 8 by pipe 26 into a stationarypan 27, whence it escapes from the machine by the outletpipe 30. Pipe 31is a drain for the cup 4. The drum 5 is rotated by means of the groovedpulley 40 on the hollow shaft 6, to which motion is imparted by a belt4l from any suitable motor.

The foregoing mechanism is fully shown and described in Letters PatentNo. 677, 926, granted to me July 9, r1901.

I will now set forth the especial features of vessel 2 is a gear 17,which engages with a gear 22, fast on the shaft 24, which is received4within the hollow shaft 6. Shaft 24 isrotated by the grooved pulley 42,to whichmotion is imparted by the'belt 43, and the lower end is receivedin a step (not shown) disposed within the fixed sleeve 39, whichV may becast integrally with standard 3.

The operation of the machine is as follows: The drum 5 and Vessel 2being set in rotation, a suiiicient quantity of liquid is poured inthrough conduit 13 to produce the liquid ring around the interior ofdrum 5, substantially as shown at a, Fig. 2. The combined constituents(solid and liquid) to be separated are then introduced through theconduit 13. As they descend into the channels 16 they are projectedtherefrom by centrifugal force against the inner surface of the rotatingperforated vessel 2. Both constituents are then carried by thecentrifugal force of rotation of drum' 5 through the conical aperturesin said vessel and against the inner wall of recep-l tacle 8 at and nearthe place of greatest eccentricity with respect to the axis of rotationof drum 5. The liquid escapes through pipe 26 to pan 27, and, as alreadystated, out of the machine by pipe 30. The solid constituent asfast asdeposited is removed by the v Scrapers traverse the inner periphery ofthe receptacle and convey the solid constituent from its place ofdeposit to the outlet-openin g. I have found that when the solid to beseparated from the liquid is light and fine in character the use ofradial scraper-arms is a disadvantage, for the reason that they operateto agitate the fluid material Within the receptacle, and thus preventits ready deposit by the action of centrifugal force. It Will be seenthat in my present device I use no central shaft having radial arms toSupport Scrapers and that the scrapers, as already explained, aredisposed on the exterior of the rotating perforated vessel. As aconsequence the liquid between the perforated vessel and the receptacleremains practically quiet, so that the ne solids are readilyprecipitated by the action of centrifugal force on the receptacle-wall.It will be noticed that the oonical apertures in the perforated vessel 2are larger at their inner ends and that there are very many of them, sothat the combined materials readily pass through them to the annularspace between the perforated vessel and receptacle.

I claim- 1. In a centrifugal machine in combination with a receptaclefor the combined constituents to be separated rotary on an eccentricaxis, a multiperforated vessel arranged to receive said constituents anddisposed within said receptacle.

2. In acentrifugal machine, in combination with a receptacle for thecombined solid and liquid constituents to be separated rotary on aneccentric axis and having an outlet-opening for said solid constituent amultiperforated vessel arranged to receive Said constituents anddisposed Within said receptacle, and means between said vessel andreceptacle for conveying the solid constituent deposited on the wall ofsaid receptacle to said outletopening.

3. In a centrifugal machine, in combination with a receptacle for thecombined constituents to be separated rotary on an eccentric axis, arotary multiperforated vessel arranged to receive said constituents anddisposed within said receptacle.

4. In a centrifugal machine, the combination of a receptacle for thecombined solid and liquid constituents to be separated having anoutlet-opening for said solid constituent and constructed to rotate onan eccentric axis, a rotary receiving multiperforated vessel for saidconstituents disposed within said receptacle, and means for conveyingthe solid constituent deposited on a portion of the inner surface ofsaid receptacle to said outlet-opening.

5. In a centrifugal machine, the combination of a receptacle for thecombined solid and liquid constituents to be separated having anoutlet-opening for Said solid constituent and constructed to rotate onan eccentric axis, a rotary receiving multiperforated vessel for saidconstituents, and means on the exterior of Said vessel for conveying thesolid constituent deposited on a portion of the inner surface of saidreceptacle to said outletopening.

6. In a centrifugal lnachine, the combination of a cylindricalreceptacle for the combined constituents to be separated constructed torotate on an eccentric axis, and a multiperforated vessel disposedWithin said receptacle and rotary on an axis concentric therewith.

7. In a centrifugal machine, the combination of a cylindrical receptaclefor the cornbined constituents to be Separated con structed to rotate onan eccentric axis, a rotary cylindrical multiperforated vessel Withinsaid receptacle and means for feeding said constituents into saidvessel.
